Plant biologist Roger Hangarter and student, Samuel Orr, of Indiana University in Bloomington knew the cicadas were coming, but the pair didn't intend to document the event until the insects began to emerge, spectacularly, in Hangarter's own backyard. The resulting five-minute film (whose original length is 17 minutes) was "a discrete, elegant package, beautifully photographed and very detailed", says panel of judges member Thomas Lucas.
